Numerical simulations and experiments of simultaneous acceleration of positive and negative ions in a radio frequency quadrupole

The simultaneous acceleration of O^{+} and O^{-} beams in a radio frequency quadruple accelerator has been numerically simulated and the results are presented in this paper. The micropulses of O^{+} and O^{-} beams have been measured in dual beam acceleration experiments, which verified the numerical simulations and feasibilities of dual beam acceleration
